Despite efforts from biotechnology companies such as Monsanto to promote GMO (genetically modified organisms) foods, a new poll announced November 12 shows that as many as 95 percent of European respondents rate GMO foods as potentially unsafe and lacking real benefits.

The European Commission survey used to determine consumer attitudes toward GMOs has seen a downward trend in GMO popularity over the last 15 years. Even Spain, which has in the past been more in favor of GMOs, saw a drop in support by 20 percent in the last five years.

The study found that 70 percent of Europeans believe GMOs are fundamentally unnatural, while nearly 60 percent believe GMOS are a threat to the health of themselves and their families. Fifty-eight percent believe GMOs are not safe for future generations.

A recent poll by The Economist in the US showed public opinion there is meeting that of Europeans, with 62 percent of respondents indicating skeptism towards GMOs. However, government regulation in the US is less stringent and many GMO products aren't labeled at all, which may affect consumer attitudes.

Want to avoid GMO foods? While labeling varies on where you live, there are some basic rules of thumb in avoiding GM products that are applicable worldwide:

Buy 100 percent organic: Some organic products (with multiple ingredients), however, may contain non-organic ingredients, so it's best to stick to single ingredients. Because something says "organic" on it doesn't mean it doesn't contain GM ingredients. In fact, it could contain up to 30 percent GM ingredients, so be sure the labels say 100 percent organic.
